摘要： The present invention provides a sleeve assembly and an optical sub-assembly, in which dimensional tolerance may be expanded for both holding the stub and inserting/extracting the ferrule. The sleeve assembly of the present invention includes a stub, a bush, a sleeve, a ring member, and a sleeve cover. The stub is held by the bush such that the bush is press-fitted between the first portion of the stub and the sleeve cover. While, the second portion of the stub is secured by the ring member through the first mating portion of the sleeve. Thus, in the present sleeve assembly, dimensional accuracy for holding the stub and that for inserting/extracting the ferrule are independent with respect to each other. Therefore, manufacturing tolerance of the sleeve assembly can be widened.
